This invention relates to locomotives and more'par'ticularly to integral frame constructions, especially for large locomotives of great power.

'In-genera-l my invention has to do with a constructioninwhich them'ainframe, the

' cylinders, crosshead' guides, guide brackets andli valve motion brackets are all cast integra Y More specifically the invention has to do with anovel disposition of the parts whereby a greatly improved construction of unitary locomotive frame structure is'secure'd.

Another object of the invention is to provide a. construction such that the cylinder structure andxthe cylinder saddle structure may be of great strengthand'rigidity and afford stiffness for the guide and valve motion sup orts.

, ow the foregoing, together with such other objects and advantages as may herein-,

after appear, or are incident to my invention, are realized is illustrated in the accompanying drawings, wherein-- Fig. 1 is a more or less diagrammatic side elevation of a locomotive provided with my improved integral frame structure.

Fig. 2 is a plan view of the frame structure.

Fig. 3 is a front elevation of Fig. 1 partly in section.

Fig. 4 is a section taken substantially on the line 4.-4 of Fig. 2.

Referring now to Fig. 1, the reference numeral 7 indicates the boiler and superstructure carried in the usual manner on the main frame indicated as a whole by the reference character A and by the frame B articulated with the main frame and transmitting pull. The drivers, of which there are more than two, are indicated at 8.

' The main frame comprises the usual side members 9 suitably connected at intervals by cross members 10 and provided with pedestal jaws 11 for the driving boxes not shown. The

-' forward end of the main frame takes the form-of a horizontallydisposed plate 12 provided with upstanding and depending ribs 13 and 14 extending longitudinally thereof in substantial alignment with the side members 9. Transverse ribs 15 and 16 respectively,

rise fromand depend belowtheplate 12 and connect the-pairs of'ribs 13 and 14 and provide a saddle structure. Similar transverse ribs 17 connect the pairs ,of'ribs 13 and 14 to the rear ofthe-saddle.

The plate 12 is widened, i. e., it projects laterallybeyond the, pairs ofribs 13 and 14 and has cast integraltherewiththe cylinders 18 and'the brackets 19forthe main crosshead guides 20. The brackets 19 have-cast integral therewith the valve motion brackets'2l.

The widened construction of the ,plate 12 makes it possible to carry pairs of ribs 22 and 23 laterally outward fromthe ribs 13 to the main cylinders 18'and valve-cylinders 18a and also makes it possible to carry similar pairsof' ribs 24 and 24a, aboveand below the plate, to the main-crosshead guide brackets and the valve motion brackets. These portions 14a of the ribs 14;, from the region of theforward ribs 15 and:16'to the side frame members9 proper, arethickened forstrength. The ribs 13 rise upwardly from each end toward the cylindersaddle (see Figs. 1 and 3) and mergewith the'padportion'of the saddle.

Thus it will be seen thata very strong, rigid and stiff front-end construction issecured by virtue of which all parts are kept in alignment under service conditions, even though normal maximum distance between cylinders-ismaintained.

I claim 1-. Anintegral locomotive frame structure comprising a main frame widened out betweenthecylinders andthe forward driversto extend laterally beyondthe planes of the drivers, and cylinders and crosshead guide brackets formed integrally with-such widened portion.

2. An integral locomotive frame structure comprising a main frame widened out between the cylinders and the forward drivers to extend laterally beyond the planes-of the drivers, and" cylinders and crosshead guide brackets formed-integrally with such widened portion, the widened portion beingprovided withreinforcing ribs joining-with the cylinder wallsand thebrackets.

' 3. An integral locomotive frame structure comprising a main frame widened out at its forward end to extend laterally beyond the planes ofthe side members of such frame, and cylinders and crosshead guide brackets formed integrally with such widened portion, the widened portion being provided with upper and lower reinforcing ribs joining with the cylinder walls and the brackets.

i. An integral locomotive frame structure comprising a main frame terminating at'its forward end in a horizontal plate-like por-' tion of greater width than the frame proper, cylinders and crosshead guide brackets marginal of the said portion, and pairs of upper and lower transverse ribs joining withthe cylinders and brackets.

An integral locomotive frame structure comprising a main frame terminating at its forward end in a horizontal plate-like portion of greater width than the frame proper, cylinders and crosshead guide bracket-s marginal of the said portion, and pairs of upper and lower transverse ribs joining with the cylinders and brackets, together with longitudinal upper and lower ribs in approximate alignnim; with the side members of the frame and intersecting the first mentioned ribs.

6. A integral locomotive frame structure comprising a main frame terminating at its forward end in a horizontal plate-like portion of greater width than the frame prop er, cylinders and crosshead guide and valve motion brackets marginal of the said portion, and pairs of upper and lower transverse ribs joining with the cylinders and brackets.

7. An integral locomotive frame structure remprising a main frame terminating at its forward end in a horizontal plate-like portion of greater width than the frame proper and intersecting ribs on the plate-like portion providing a reinforced saddle portion.

8. An integral locomotive frame structure comprising a main frame terminating at its forward end in a horizontal plate lilte portion of greater width than the frame proper and intersecting ribs on the plate-like portion providing a reinforced saddle portion having cylinders integral therewith.

9. An integral locomotive framestructure comprising main frame terminating at its forward end in a horizontal plate-like portion of greater width than the frame proper and longitudinal and transverse upper and lower intersecting ribs integral therewith, the transverse ribs starting at points laterally outside the planes of the side members of the frame.

10. An integral locomotive frame having those portions which are provided with pedestals located ithin the planes occupied by the driving wheels and having that portion which extends forward of the driving wheels between said wheels and the cylinders widened laterally beyond such planes to carry the cylinders and carried upwardly to provide a saddle.

11. An integral locomotive frame having those portions which are provided with pedestals located Within the planes occupied by the driving wheels and having that portion which extends forward of the driving wheels bet-ween said wheels and the cylinders widened laterally beyond such planes to carry the cylinders and carried upwardly to provide a saddle, and cylinders cast integral with such widened portion.

12. An integral locomotive frame having those portions which are provided with pedestals located within. the planes occupied by the driving wheels and having that portion which exten'dsforward of the driving wheels between said wheels and the cylinders widened laterally beyond such planes to carry the cylinders and carriedupwardly to provide a saddle, said widened portion having cast integral therewith the cylinders and the cross-head guide supports.

. 13. An integral locomotive frame having those portions which are provided with pedestals located within the planes occupied by the driving wheels and having that portion which extends forward of the driving wheels between said wheels and the cylinders videned laterally beyond such planes to carry the cylinders and carried upwardly to provide a saddle, said widened portion having cast integral therewith the cylinders and the cross-head guide supports and the valve mos tion supports. 1

In testimony whereof I have hereunto signed my name.
